“…1) and the total lipid contents in the above study and suggested the presence of growth inhibitors in the recycled media. Microalgal cells may have responded to the growth inhibitors by forming aggregates, thereby resulting in a lower light utilization efficiency and thus lower growth rates and lower total lipid contents [29].…”

A b s t r a c t. The effects of the phytohormone indole-3-acetic acid and various conditions of illumination on the growth of Parachlorella kessleri were investigated. Two variants of illumination: continuous and photoperiod 16/8 h (light/dark) and two concentrations of the phytohormone -10 -4 M and 10 -5 M of indole-3-acetic acid were used in the experiment. The results of this study show that the addition of the higher concentration of indole-3-acetic acid stimulated the growth of P. kessleri more efficiently than the addition of the lower concentration of indole-3-acetic acid. This dependence can be observed in both variants of illumination. Increased biomass productivity was observed in the photoperiod conditions. Both the addition of the phytohormone and the conditions of the illumination had an impact on the number of P. kessleri cells. An increased number of cells was observed under the conditions of continuous illumination. This result has shown that the continuous illumination and the higher concentration of the phytohormone stimulated the growth of P. kessleri more effectively than the shorter duration of light (16/8 h (light/dark)).K e y w o r d s: light, photoperiod, microalgae, indole-3-acetic acid, Parachlorella kessleri

“…Krzemińska et al. detected that the percentage of C16 decreased from 18.11 to 15.24% and the percentage of C18 increased from 61.71 to 73.7% with the of light intensity from 130 μmol/m 2 /s to 420 μmol/m 2 /s in the culture of C. protothecoides . This result indicated that higher light intensity is benefit for the accumulation of FA with longer carbon chains.…”

Botryococcus braunii was cultured in different light path length under different incident light intensity to investigate the effect of light on alga growth as well as hydrocarbon and fatty acid accumulation. Results indicated that longer light path length required higher incident light intensity in order to meet the light requirement of algal growth and hydrocarbon accumulation during the course of cultivation. However, hydrocarbon profile was only affected by the incident light intensity and not influenced by the light path length. High incident light intensity enhanced the accumulation of hydrocarbons with longer carbon chains. Besides, the fatty acid content and profiles were significantly influenced by both incident light intensity and light path. Higher fatty acid content and higher percentage of C18 and monounsaturated fatty acid components were achieved at the higher incident light intensity and lower light path length. Taken together, these results are benefit to improve its biomass and oil productivity through the optimization of light and photobioreactor design.
